  • Patent number: 7537829
    Abstract: Multi-layer films that are suitable for packaging and having improved sealing properties are disclosed. Some embodiments may also provide a lower minimum sealing temperature. A soft polymer is blended in a core layer and a tie layer comprising the soft polymer and, optionally, another polymer. A sealable layer is provided on the side of the tie layer opposite the core layer. The multi-layer films may be transparent, contain a cavitating agent, or are pigmented to form an opaque film. Also, the multi-layer film may be metallized or coated with a barrier coating.

  • Patent number: 7514131
    Abstract: An in-mold label includes a thermoplastic resin film substrate layer and a heat-seal resin layer. The label has a label body and a separable part. Tearable perforations are provided between the label body and the separable part. The adhesion strength between the separable part and a thermoplastic resin container is from 80 to 270 gf/10 mm, when the label is stuck to the container during in-mold production of the container. A lubricant is applied to from 55 to 80% of the surface area of the heat-seal resin layer of the separable part. The wettability index of both the thermoplastic resin film substrate layer surface and the heat-seal resin layer surface is from 34 to 73 mN/m.
